DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observationsmade during the 2011/2012 and 2013/2014 growing seasons at Clanwilliamand Wellington, South Africa of vines planted in 2008 on ‘Ramsey’rootstock (not known to be patented). It should be understood that thecharacteristics described will vary somewhat depending upon culturalpractices and climatic conditions, and will vary with location andseason. Quantified measurements are expressed as an average ofmeasurements taken from a number of individual plants of the newvariety. The measurements of any individual plant or any group of plantsof the new variety may vary from the stated average. Color descriptionsare made with reference to The Royal Horticultural Society Colour Chart(5^(th) Edition).
